Nothing traumatizes homeowners like seeing crabgrass and other weeds invade their lawns. These unwanted plants can damage your turf quickly, so taking precautions as early as possible is necessary. You can fix the problem by spraying the lawn with chemical herbicides or home remedies like baking soda. This article will discuss the process of killing crabgrass with baking soda. Keep reading to learn more.

To kill crabgrass with baking soda, wet the weeds first, then cover the surrounding plants to avoid damaging them. Apply enough baking soda to these weeds and allow it to sit for a few hours for better absorption. Afterward, use your hand, weed remover, or a shovel, to remove dead crabgrass and reseed the patches. Leaving the spots bare after removing crab grass encourages the growth of more new weeds.

How to Kill Crabgrass with Baking Soda

Killing Crabgrass with Baking Soda

Baking soda crabgrass killer makes the leaves, stems, and roots dry, thus damaging and killing the plants’ tissues. Here are the crabgrass prevention steps using baking soda;

1. Water the crabgrass

Use a garden hose or sprinkler to wet areas with crabgrass. Don’t water the lawn if you’re applying this chemical in the morning or during the rainy season when the grass is wet. This water helps the baking soda to stick effectively to the plant surface for better results.

2. Cover neighboring plants

Baking soda kills crabgrass and other plants as well. So, cover the surrounding crops with cardboard before applying this chemical to crabgrass.

3. Apply baking soda

Sprinkle all infested areas with a fair amount of baking soda for maximum effects. Apply multiple times to areas with too much crabgrass.

4. Leave the baking soda to sit for a few hours

Once you spray these unwanted weeds with the crabgrass killer, allow the baking soda to sit for a few hours. This helps in the absorption of this chemical by plant roots.

5. Remove crabgrass

Use a shovel or weed remover to remove crabgrass once the plants turn black or brown. Pull them properly to prevent the sprouting of new weeds.

6. Reseed the bare spots

Reseed all the bare patches once you remove the crabgrass. Leaving these spots without grass for long will encourage the growth of new weeds.

So, pull out those crabgrass shoots carefully without damaging the turf. Doing this at an early stage helps get rid of crabgrass from your yard effectively. If you wait for these weeds to mature before you remove them, they might scatter their seeds all over the lawn.

Therefore, it’s a good idea to conduct crabgrass removal when the plants are still young or when you spot them.
